"Starites are magical objects born out of the happiness of others..."
Scribblenauts is one of my favorite games. This is saying something because up until Unlimitied, I'd only barely play the actual "game". The start screen sandbox mode is all you need to have a good time with the first two. Unfortunately, sandbox mode is left out in Unlimited, or at least in the 3DS version. I haven't played the console/PC versions yet. I suppose Edwin's farm could be a sandbox, but then I'd feel bad since I've got Lily turning into stone standing there waiting for me to save her.
Scribblenauts was an easy series to make PACs out of since all the really notable characters pretty much look the same.
